When to have a 5D ultrasound? Best week and how to prepare
Between weeks 24 and 30 the baby's face is seen best. What affects image quality, how to prepare and how it differs from 4D.
Seeing your baby's face, expressions and movements is one of the most exciting moments of pregnancy. 5D ultrasounds produce images with a more defined, natural look than traditional two-dimensional ultrasounds, which is why many families choose to book a session as a keepsake of this stage.
However, one of the most common questions is: when is the best time to get a 5D ultrasound?
Although it can be done at different points during pregnancy, the quality of the images depends on the week of gestation, the baby's position, the amount of amniotic fluid and other factors. That's why choosing the right time can increase the chances of clearly seeing their face and movements.
What is the best week for a 5D ultrasound?
In many cases, the period roughly between weeks 24 and 30 of pregnancy tends to offer a good balance between the development of facial features and the space available inside the womb.
During these weeks:
The baby's face is more defined.
They start to build up more tissue under the skin.
There is still some space to move around.
It's possible to observe expressions, yawns, hand movements or changes in facial expression.
However, there is no perfect week that works the same for every pregnancy. The recommendation can vary depending on the position of the placenta, the type of pregnancy and each patient's individual characteristics.

5D ultrasound before week 24
Having the session before week 24 allows you to see a larger part of the baby's body and easily observe their movements.
At this stage the baby still looks slimmer and their features are not as rounded. So, although the images can be very lovely, they usually offer less facial detail than those obtained a few weeks later.
An early ultrasound can be appealing for families who want to watch the baby's movements or follow their progress, but it isn't always the best time to get detailed close-ups of the face.
5D ultrasound between weeks 24 and 30
This period tends to be the most requested for emotional ultrasounds.
By now the baby's facial features are well formed and they start to look more like they will at birth. At the same time, there is usually still enough space to change position.
Among the images that can be observed are:
- The profile and features of the face.
- Hands near the face.
- Smiles or mouth movements.
- Yawns.
- Arm and leg movements.
- Changes in posture.
- Facial expressions.
The final sharpness will depend on the face not being covered by the hands, the umbilical cord, the placenta or a limb.
Can a 5D ultrasound be done after week 30?
Yes, it can also be done during the final weeks of pregnancy.
From week 30 onwards, the baby usually has more rounded, defined features. Sometimes very expressive, detailed images can be obtained.
However, there is also less space inside the womb, so it can be harder to find a completely clear angle. If the face is turned towards the mother's back or is very close to the placenta, the images may be less visible.
For this reason, when the main goal is to get a clear keepsake of the face, it is usually recommended not to leave the session for the final weeks.
What factors affect the quality of the images?
The week of gestation is important, but it is not the only element that determines the result.
The baby's position
The baby may be facing the mother's back, covering their face with their hands or placing their feet in front of their face. In these situations, getting a frontal image can be difficult.
Sometimes walking for a few minutes or changing position helps them move, although this doesn't always happen right away.
The location of the placenta
When the placenta is at the front of the womb, it can sit in front of the baby's face and make some angles difficult.
This doesn't mean the ultrasound can't be done, but it can affect visibility.
The amniotic fluid
The fluid surrounding the baby helps transmit the sound waves and produces more defined images. The amount and distribution of the fluid can influence the result of the session.
The space available
As pregnancy progresses, the baby takes up more of the womb. This makes it possible to see more developed features, but reduces the room for finding clear positions.
The characteristics of each pregnancy
Every pregnancy is different. Abdominal tissue, multiple pregnancies, foetal position and other factors can affect the quality of the images.
For this reason, a 5D ultrasound can never guarantee a specific photo or a fully frontal view of the face.
How to prepare for a 5D ultrasound
In general, no complex preparation is needed. However, a few simple recommendations can be followed.
Keep up normal hydration
It's a good idea to stay properly hydrated in the days beforehand, always following the usual pregnancy recommendations. There's no need to drink excessive amounts of water right before the appointment.
Eat normally
Unless the centre or the healthcare professional advises otherwise, you can eat normally before the session.
Wear comfortable clothing
The scan is performed on the abdomen, so it's a good idea to wear clothes that allow easy access to that area.
Arrive with time to spare
Arriving without rushing helps you enjoy the experience calmly. When the baby is not in a favourable position, it may be necessary to wait a few minutes or try to get them to change position.

What is the difference between a 2D, 3D, 4D and 5D ultrasound?
A 2D ultrasound is the traditional black-and-white image commonly used during pregnancy monitoring.
A 3D ultrasound reconstructs an image with volume from the information obtained through ultrasound waves.
A 4D ultrasound allows those three-dimensional images to be seen in motion, in real time.
The term 5D is usually used for processing systems that improve lighting, texture and the perception of depth, producing images with a more natural look.
Does an emotional ultrasound replace medical ultrasounds?
No. An emotional ultrasound is mainly intended to let the family see the baby and keep images or videos as a keepsake.
It does not replace:
- Diagnostic pregnancy ultrasounds.
- Gynaecological check-ups.
- Prenatal screening tests.
- Follow-up carried out by the midwife or obstetrician.
- The medical guidance set for each pregnancy.
It's important to keep all scheduled prenatal check-ups, even if a 5D ultrasound session is booked.

Frequently asked questions
In which week is the baby's face seen best?
Good images are frequently obtained between weeks 24 and 30, although visibility depends mainly on the baby's position and on the characteristics of each pregnancy.
What happens if the baby won't let us see them?
It may be that the baby has their hands in front of their face, is facing backwards or is very close to the placenta. The specialist may suggest walking, changing position or waiting a few minutes to see whether the baby moves.
Can I bring people with me?
The conditions depend on the space available and the clinic's policy. It is advisable to ask when booking the appointment.
Is a 5D scan useful for detecting medical problems?
Emotional sessions should not be used as a substitute for a diagnostic examination. Any doubt about the baby's health or development should be discussed with the gynaecologist or obstetrician.
Can it be done in a twin pregnancy?
Yes, although it is usually recommended somewhat earlier because the babies have less room as the pregnancy progresses.
